Crawl Space Encapsulation
If you've got a crawl space under your home or business, you know it can be problematic when it comes to moisture and humidity. It also probably houses some important systems for the building including the heating and cooling. Being sure this area is both protected from the elements and is in a controlled environment will not only help keep the equipment there in better working order, but it will control the humidity in the area which can prevent the growth of mold as well as protect you from sagging floor joists.
The best way to protect the crawl space is to completely seal it off using what is known as a crawl space encapsulation system. These systems are a combination of products that are specifically designed for moist crawl spaces and have proven themselves time and time again over the years. The main pieces of the system are the vapor barrier which goes along the walls and floors of the crawl space, an air tight door and vent covers, the water control and diversion system, a sump pump, and a dehumidifier. With these products installed, you can be sure your crawl space will no longer have issues with excess water or high humidity.
The vapor barrier is one of the most important parts of the encapsulation system because it is preventing the excess water and moisture from entering the area. Constructed of high quality reinforced polyethylene resin, it is specifically designed for crawl spaces to be absolutely waterproof and able to resist mold and mildew growth. This material is laid out along the entire crawl space floor and up the walls to the floor joists to completely seal the area from the outside environment.
Vapor barriers come in different thicknesses depending on their ultimate usage. The flooring can be a variety of thicknesses so if you intend on using the crawl space as additional storage, a thicker floor option is available. The walls are also thinner, but equally as waterproof and resistant to mold, because they do not need to support any weight or wear and tear.
We make use of a special dehumidifier for the crawl space. Once the water is being kept out of the area, we only need to focus on preventing excess moisture from causing potential damage to the equipment and floor joists. By installing a crawl space dehumidifier we can ensure the area is kept at a proper humidity level.
We use Dow spray foam insulation in crawl spaces as well as basements to seal out excess air and moisture in confined or awkwardly shaped areas where the vapor barrier cannot work like the top of walls and inside the floor joists. This will create a barrier that not only keeps the moisture out but also add an extra layer of insulation.
This expanding spray foam insulation, once applied, will expand to fill all of the small gaps and crevices around the floor joists and wall cavity. This will help create a barrier against the outside weather and make the interior of your crawl space, or basement, a much more suitable environment that is protected from the elements and can better maintain proper temperature control.
